From igcm at admws.idaho.gov Tue Jun 29 07:55:14 2021 From: igcm at admws.idaho.gov (Idaho Geospatial Council Membership) Date: Tue, 29 Jun 2021 13:55:14 +0000 Subject: [IGCM] Review Parcel Standard and upcoming Parcel Technical Working Group Message-ID: Good morning, We want to thank those people that attended the Parcel Technical Working group yesterday and provided valuable feedback to the second version of the parcel data exchange standard. The first version was published in 2010, and we have made a number of changes to the exchange standard as well as to the vision on how we can get closer in Idaho to making access to parcel data easier. You can find a recording of yesterday's parcel TWG here if you would like to hear an overview of the latest version, the changes that were made it, and a discussion surrounding this draft. Before starting, I do want to emphasize that we are not expecting the counties to format or change their data. The plan is to take the data as is (i.e. the way it comes out the CAMA system) and then standardize the names (i.e. the column headers) and consolidate at the State level. The biggest changes to the standard (pasted below): 1. The new proposed version of the Parcel Data Exchange Standard (updated to reflect comments from yesterday's TWG) includes 3 datasets: * A parcel polygon layer with attributes related to the entire parcel (see screen capture of the proposed schema below) * A parcel point layer displaying parcel centroids (as calculated using GIS tools) with the same attributes as the parcel layer * A table with improvement information where each row in the table corresponds to one improvement (new in this standard) 2. Discussion point from yesterday's TWG: we will try to provide the consolidated data as individual layers, but also as a service where the improvements are related to the parcel they reside on 3. The attributes in white shown below can only be obtained from the counties, the ones shown in orange can be added during the consolidation process by the State 4. The assessment categories have been simplified - only one attribute field that includes all assessment categories rather than having those separated into different fields along with the acreage and value of each. 5. Description (e.g. "Tax 1234" or "Cottonwood Subdivision Block 5 Lot 3" or NWSE of Section 3 in T34N R23E") used to have 5 fields (Description 1, 2, 3 ...) has been reduced to just one field called "LGL_DESCR". 6. The Subdivision (people can just look this up in the LGL_DESCR field) and Zoning (that should be a standard and dataset separate from the parcel standard) have been removed. 7. The Updated date (i.e. the most recent date the parcels are current, i.e. when a snapshot of the parcels have been taken) remains. However the Modified date (when each parcel was last edited) is taken out because many counties do not keep track of that and if you really want to know the history of a parcel you should research the legal documents behind it) 8. There are a number of new fields: * PUBLIC_STD: One field where the names of public agencies are standardized. So for example, "BLM", "DOI BLM", etc. are all translated into "Bureau of Land Management". * Centroid Coordinates: LAT_DD, LONG_DD, IDTM_N, IDTM_E * VAL_LAND and VAL_IMPVTS, i.e. the value of land and improvements. We had a discussion about whether those should be gross values, or the values that remain after deducting any exemptions. To support emergency management we landed on the side of gross values. * HOME_EXMPT: this field contains either True or False depending on whether there is a home exemption on the field or not (again, this will support emergency management) Other discussion points: 1. Unlike the last time, the State should not be involved in any money transactions. We think this will greatly simplify the process and increase our chance of success. One thought is to have people that want parcel data work directly with the counties to get permission / make a payment if needed / sign forms as counties are currently doing. Then, once granted permission to the data, the county can notify the State to allow access to their parcel data. 2. Last time we had a public standard with a reduced number of attributes (basically just the shape and the PIN number) that is free to the public (note that we are not telling the counties to participate. We would like them to, but off course that is up to the county who is the steward of the data) as well as a comprehensive standard that was free for government agencies, but that may require payment or additional agreements. We need to further determine whether we want to stick with that model, or if there is only 1 data standard and individual counties determine which attributes can be made publicly available, and which ones cannot. What's next? * If you are parcel data consumer or producer, please read the latest version of the new parcel standard document and provide comments to Betty Conces and Wilma Robertson before July 14. * Attend our next Parcel Technical Working group meeting on Monday July 19 from 2-3 PM where we will: * Finalize the parcel standard (depending on the severity of the comments) and hopefully be able to have the IGC-EC approve it during their July 22 IGC-EC meeting. * Demo a parcel sharing pilot project and discuss how to move forward * Figure out how we can get buy-in from counties * Talk about the type of agreements that need to be in place between counties, ITS and parcel data consumers Attributes for Parcels polygon and Parcel Centroid layers Attributes in orange can be calculated or added by the State.
